My point about men grooming was mostly to say that if they want women to do it, they should do it, too. No reason for it, just as there's no real reason for women to do it.
Synthetic materials are the enemy, for sure. Even if the clothing is loose, synthetic underwear is problematic.
Women have smells. Men do, too. None of us smell clean and fresh all the time - that's normal. If a quick clean up doesn't help, it's a sign that something isn't right.
